There are no signatures. There are no technicolored, multi-break memorabilia pieces. But what Panini America’s captivating Kaboom! insert might lack in the area of autographs and game-worn, it more than makes up for in all the ways that matter. Like, flashy technology . . . and needle-in-a-haystack rarity . . . and a cult-like following . . . and a penchant for making the NBA’s high-flying stars seem just a little more super and heroic.

It’s Kaboom!, perhaps more than any other aspect, that has helped make Excalibur Basketball a hit. In fact, the hobby-only premium edition of 2015-16 Excalibur Basketball was sold out upon release earlier this week. Granted, there are many things to like in the newest iteration of Excalibur, but it’s the super-rare, super-cool, super-hero inspired Kaboom! (which appears in both hobby and Target-only retail versions of Excalibur) that causes the biggest commotion.

This year’s insert features 25 new original illustrations, including four rookies and six legends. But since the cards appear roughly once in every two cases, it’s likely that many collectors have yet to see every card in the set. That changes today. In the gallery that follows, we offer a must-see visual checklist that includes photos of each Kaboom! card as well as flat scans of both the fronts and backs.

Still, even these varying glimpses are no substitute for the full Kaboom! experience that takes place when you hold one of these babies in your hands. Enjoy the gallery and stay tuned to The Knight’s Lance for continued coverage.
